How does this fix work exactly? I am not following.

I had my VC 1.6 installed and it WAS working with Button 5. Then stopped, so I mapped it to my "Start" button.... COOL...

So then I installed the patch and I had to RE-INSTALL my VC 1.6

But then Button 5 worked like a charm after the reinstalled.

Then MAGICALLY after a few weeks, it stopped working?!

What gives
